To all whom 1f may concern.'

e it known that I, Josera AMUso, a citizen of the United States, residing in Pit-ts field, inthe county of Berkshire and State ofliflassacliusetts, have invented certain. new and useful improvements in Lubricators, of which the following is a specification, refeienc/e being had therein to the accompanying drawings.

dy invention relates 'to means for oiling or lubricating journals and other bearings, and provides a system whereby one or more journals or bearings may be supplied With a lubricant., and operated by means of a pressure system.

Another object of the device is to provide means whereby the pressure on the lubricant Stil 'of 2 showing the 'carry the lubricant to reservoir may' be released and the reservoir refilled with the'lubricant material.

Figure l represents a side elevation oit the device. Figure 2 is an elevation view of 'the lubricant reservoir. Figure 3 is a vertical section through the reservoir and pressure supply pipe, and Figure Il is a bottom vieu7 arrangement of the tubes.

"il/eferringto the drawings by numerals, 1 designates cylindrical reservoir of suitable material, prersrably glass, which may be of any eine, and the said reservoir is mounted the casing 2. v

'lhe easing 2 is provided with a screw cover l on the bottom, and the upper part of 'the reservoir is also provided with a screw cover 3. l gasket 19, of suitable man terial, is placed between the reservoir and the upper and lower covers thereby assuring an air tight enclosure Within the reservoir. rl`he lower cover el is provided with a plurality of .tubes 13 to provide means to the various journals and bearings. rlhe top cover is also provided with a projection le to provide means to connect the pressure supply pipe 5. The pressure supply pipe 5 is provided with a globe valve 11 and also a eoclg 12.

`A piston 6 is slidably fitted 1n the reservoir and is operated by means of the pressure from the pressure supply pipe 5. The piston rod 7 is provided with a pin 8 to provide means to hold the spring 9 in position. The lower-end of the pressure supply pipe is also provided with two pins l0 to provide Isupporting ineans for the spring' 9.

As a. means to ascertain the amount of -lubricantfwithin the reservoir, I have pro- Seral No. 751,7.

vided a slot 2O in the outer reservoir proper consisting of some transparent material, it Will be seen that the amount of lubricant in the reservoir can be readily ascertained. lille( at any time by removing the screw plug '18.,

pressure reservoir i5 is placed above or along side of the lubricator and fastened by a brace 17 or other means. The pressure reservoir is also provided with a pressure gauge 16. This reservoir provides the means whereby the lubricant is forced through the 'tubes The device is operated as follows: The reservoir is illed with lubricant and the casing 2, and the y The reservoir may be' tubes 13 are carried to the various journals `Y and bearings. lt' necessary the tubes may be equipped with valves to regulate the supply, or the number' of tubes to be used. The globe valve 11 is opened and the air pres` sure from the reservoir 15 passes through the pressure supply pipe 5, and the air being under pressure is exerted ou the piston 6 and forces the piston in a downward position in the reservoir cylinder, and this action forces the lubricant through the tubes. which causes it' also compresses The pressure on the piston, to move along the reservoir the spring 9.

After the pistou 6 lower end of the reservoir cylinder, and it is desired to refill the reservoir With, lubricant, the globe valve 11 is closed and the cock l2 is opened releasing the air Within the reservoir and the pressure supply pipe 5.' When the air pressure is released the tension yon the spring 9 will cause the sume its original position.

It will be seen that the peculiar construe-v tion of my invention makes it readily adaptable to oiL or grease the journals and bearings on aireutoinobile, and by using hot air 'n the pre sure reservoir the oil and grease in the lubricator may be maintained it to freely iow through,

state that will cause the tubes 13.'
